Abstract: A system and method for interfacing external processes to a transaction processing system. An interface system is provided that accepts input messages from external processes wherein in the input messages are to be processed by a transaction process-ing system. The interface system logs received messages and notifies the transaction processing system that a message has been received for processing. The interface system sends a confirmation to the external process indicating that the message has been received. The interface system periodically examines the status of each message as it is being processed by the transaction pro-cessing system. Output status messages indicative of such status are created, stored, and sent to an external destination for infor-mational purposes. Outbound data messages are created, stored and sent to an external application. The interface system is event driven, but includes a monitor subsystem to time the start-up of certain processes at periodic intervals.

Abstract: A hand-held power-operated hedge trimmer for trimming plant growth such as hedges, shrubs, tree branches and the like. The hedge trimmer includes a housing containing a motor assembly, a blade assembly extending forwardly in a lengthwise direction from the housing, and a drive mechanism for coupling a movable cutting blade of the blade assembly to an output of the motor assembly for causing reciprocatory rectilinear movement of the movable cutting blade relative to a stationary combing blade in response to selective actuation of the motor assembly. The cutting blade includes a series of cutter teeth formed along its opposite longitudinal edges with each cutter tooth having a compound tooth profile. The compound tooth profile includes a pair of shear tooth segments formed along opposite lateral edges of the cutter tooth and a saw tooth segment formed at its distal edge between the shear tooth segments. In addition, a series of sizing lugs are formed along the opposite longitudinal edges of the movable cutting blade between each pair of adjacent cutter teeth for establishing entrapment channels therewith. In operation, smaller twigs and branches are drawn into the entrapment channels and into alignment with the adjacent shear tooth segment for shear-cutting with a single stroke of the cutting blade. The sizing lugs prevent larger branches from being drawn into the entrapment channels so as to align them relative to the saw tooth segments for saw-cutting with a multi-stroke sawing action.

Abstract: A collaboration system that integrates separate real-time and asynchronous networks - the former for real-time audio and video, and the latter for control signals and textual, graphical and other data - in a manner which closely approximates the experience of face-to-face collaboration. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations (12) and their interconnecting LANs (10) and WANs (15). In the case of a plurality of geographically dispersed LANs (10) interconnected by a WAN (15), the demands made on the WAN are significantly reduced by employing multi-hopping techniques, including avoiding the unnecessary decompression of data at intermediate hops, as well as video mosaicing and cut-and-paste technology.

Title: Debris manipulating and clearing assembly for clearing crop residue from soil
Inventor: RAWSON RAY
IPC: A01C5/06
Filed: 1996-04-03
Granted: 1999-11-30
Abstract: An apparatus and process for manipulating and clearing crop residue or other debris from a zone of soil before tilling the zone of soil to form a seedbed.  The apparatus may be attached to the tool bar of a farm implement and includes a pair of fingered wheels which are rotated by the ground and manipulate the crop residue as the apparatus moves along the ground.  A rotating coulter blade is disposed behind and between the wheels, and the wheels pull the residue rearward and press it against the soil surface where it is cut by the rotating coulter blade.  The coulter blade cuts the residue into several portions at least some of which are thrown outward away from the zone of soil to be tilled.  A zone tillage apparatus then tills, mixes, aerates and fertilizes the soil in the zone to form a fertilized seedbed, and a planter places seed in the seedbed, all of these procedures being carried out in one pass along the soil.

Title: Filter for speech modification or enhancement, and various apparatus, systems and method using same
Inventor: TASAKI HIROHISA
IPC: G10L19/26
Filed: 1996-05-02
Granted: 2000-07-25
Abstract: A  speech  modification  or  enhancement  filter,  and apparatus, system and method using the same.   Synthesized speech signals are filtered to generate  modified synthesized speech signals.   From spectral information represented as a multi-dimensional vector, a filter coefficient is determined so as to ensure that formant characteristics of the modified synthesized speech signals are enhanced in comparison with those of the synthesized speech signal and in accordance with the spectral information.    The spectral information can be any one of LSP information, PARCOR information and LAR information.  A degree of freedom of design of the speech modification filter used for the aural suppression of quantizing noise contained in the synthesized speech signals is thus heightened leading to the improvement of intelligibility of said synthesized speech signals.   A good formant enhancement effect can be obtained without allowing any perceptible level of distortions to occur within a range of permissible spectral gradients.
